Standalone Sven Coop Half-Life Coming

The Sven Co-op website has details on how
the Sven Co-op mod for the original Half-Life is becoming a standalone game, as
Valve is granting the team behind the modification access to the full Half-Life
source code to create a custom version of the engine. The standalone game will
be offered for free on Steam, and will not require ownership of the original
Half-Life (though it's hard to imagine someone would be interested in this
project but would not pay the $2.49 it would cost to get the game right now
on Steam). Word is: "Full
engine access will allow many previously impossible features to be added to the
game, as well as new functionality for Half-Life's level editor, Hammer.
Features such as Steam achievements will also be possible." No ETA for the
standalone edition is offered yet.
